I am currently working on creating a blog for my GF, and I'm trying to get the custom 404 pages to work, but they only work sometimes.
I went to the codex and read this thread and I tried what they said and different variations, but when I test the 404 it sometimes works, and sometimes doesn't.
Here is the URL: http://www.amandajeankelly.com
I am going to create a section called books and one called contact. The links are already on the navbar, but the pages don't exist yet, so use those to test the 404 page.
Try clicking on either of those pages a few times. Sometimes the 404 works, other times it doesn't.
If anyone can help me figure out what the problem is, I'd greatly appreciate it.
